Ebook Fundamentals of materials science and engineering (5th edition): Part 2

(BQ) Part 2 book "Fundamentals of materials science and engineering" has contents: Structures of metals and ceramics, polymer structures, imperfections in solids, mechanical properties, deformation and strengthening mechanisms, phase diagrams, phase transformations,.and other contents. | Appendix A / The International System of Units (SI) U nits in the International System of Units fall into two classifications: base and derived. Base units are fundamental and not reducible. Table lists the base units of interest in the discipline of materials science and engineering. Derived units are expressed in terms of the base units, using mathematical signs for multiplication and division. For example, the SI units for density are kilogram per cubic meter (kg/m3). For some derived units, special names and symbols exist; for example, N is used to denote the newton, the unit of force, which is equivalent to 1 kg-m/s2. Table contains a number of the important derived units. It is sometimes necessary, or convenient, to form names and symbols that are decimal multiples or submultiples of SI units. Only one prefix is used when a multiple of an SI unit is formed, which should be in the numerator. These prefixes and their approved symbols are given in Table . Symbols for all units used in this book, SI or otherwise, are contained inside the front cover.
